Bug in fortran compiler on Alpha

[Dr Scilab]

 In proting the new version of Scilab to Linux Alpha, we
 encountered a bug in the fortran compiler.
 This may not be the right place to report this bug, but since
 I don't know where is, here it goes.

      subroutine rpoly()
      real a,b,c
      a=amin1(b,c)
      end

f77 -v
Reading specs from /usr/lib/gcc-lib/alpha-redhat-linux/egcs-2.90.27/specs
gcc version egcs-2.90.27 980315 (egcs-1.0.2 release)

f77 -mieee-with-inexact  -c  rpoly.f
rpoly.f: In subroutine `rpoly':
rpoly.f:4: internal error--unrecognizable insn:

        (lt:DF (float_extend:DF (reg:SF 69))
            (float_extend:DF (reg:SF 70)))) -1 (nil)
    (nil))
f77: Internal compiler error: program f771 got fatal signal 6
